 // Copyright 2010-2012, Anthony Hand
 //
 // File version date: April 23, 2012
 //		Update:
 //		- Updated DetectAmazonSilk(): Fixed an issue in the detection logic.
 //
 // File version date: April 22, 2012 - Second update
 //		Update: To address additional Kindle issues...
 //		- Updated DetectRichCSS(): Excluded e-Ink Kindle devices.
 //		- Created DetectAmazonSilk(): Created to detect Kindle Fire devices in Silk mode.
 //		- Updated DetectMobileQuick(): Updated to include e-Ink Kindle devices and the Kindle Fire in Silk mode.
 //
 // File version date: April 11, 2012
 //		Update:
 //		- Added a new variable for the new BlackBerry Curve Touch (9380): deviceBBCurveTouch.
 //		- Updated DetectBlackBerryTouch() to support the new BlackBerry Curve Touch (9380).
 //
 // File version date: January 21, 2012
 //		Update:
 //		- Moved Windows Phone 7 to the iPhone Tier. WP7.5's IE 9-based browser is good enough now.
 //		- Added a new variable for 2 versions of the new BlackBerry Bold Touch (9900 and 9930): deviceBBBoldTouch.
 //		- Updated DetectBlackBerryTouch() to support the 2 versions of the new BlackBerry Bold Touch (9900 and 9930).
 //		- Updated DetectKindle() to focus on eInk devices only. The Kindle Fire should be detected as a regular Android device.
 //
 // File version date: August 22, 2011
 //		Update:
 //		- Updated DetectAndroidTablet() to fix a bug introduced in the last fix! The true/false returns were mixed up.
 //
 // File version date: August 16, 2011
 //		Update:
 //		- Updated DetectAndroidTablet() to exclude Opera Mini, which was falsely reporting as running on a tablet device when on a phone.
 //		- Updated the user agent (uagent) init technique to handle spiders and such with null values.
